This is the single most important health fact for the breed: Bedlington Terriers are predisposed to copper toxicosis, a hereditary liver disease where excess copper builds up and causes progressive liver damage — historically affecting 26-46% of some breed populations before genetic screening reduced its prevalence. A DNA test can identify carriers, and affected dogs need a low-copper diet managed under veterinary guidance for life. The breed is also prone to patellar luxation and retinal dysplasia.
Dogs with copper toxicosis need a specifically low-copper diet — this is a genuine, non-negotiable dietary requirement for affected dogs, not just a general health tip, and should be managed with a vet.
The distinctive curly coat needs professional grooming roughly every 6-8 weeks to maintain its characteristic lamb-like shape, plus regular brushing between trims.
Bedlington Terriers are affectionate, obedient, and generally easy to train — quieter and calmer indoors than most terriers, though genuinely ruthless with small prey animals given the breed's hunting history.
The Bedlington Terrier is named for the mining town of Bedlington in northeast England, originally bred to hunt rats and mice in mines before proving equally capable against rabbits, foxes, badgers, and otters — the breed's ancestry includes Whippet, Dandie Dinmont Terrier, and Otterhound bloodlines, which shows in its unusual, lamb-like curly coat and arched topline.
Sometimes called the "lamb dog" for its distinctive silhouette, the Bedlington is considered one of the least classically "terrier-like" terriers — calm and quiet as a house pet, but genuinely relentless when hunting the game it was bred to pursue.
